Definitions
- the invention relates to the use of ⁇ -aminolevulinic acid (ALA) for the manufacture of a topical drug for integral Diagnosis and / or therapy of tumors in hollow organs.
- ALA ⁇ -aminolevulinic acid
- Malignant tumor diseases in hollow organs such as Urinary and respiratory tract, peritoneal cavity, gastrointestinal tract and female genital tract, are characterized by high relapse and Progression rates. These are already in sync existing precancerous and cancerous changes (early carcinomas), which cannot be diagnosed endoscopically and therefore in cannot be treated at an early stage.
- a prerequisite for curative treatment is to comprehensively recognize all tumor areas, on the other hand, one complete and integral treatment of the entire bladder mucosa required.
- Photodynamics As an alternative to conservative diagnostic and therapeutic methods photodynamics is used. It is based on light absorption through a chemical compound, the so-called Photosensitizer, leading to fluorescence emission leads, which can be used for diagnosis and on the other hand produces a cytotoxic response that is necessary for the therapy of Benefit is.
- the therapeutic benefit is more intravenously administered Photosensitizers also due to the low tumor selectivity restricted and local side effects, like shrinking bubbles observed.
- ⁇ -aminolevulinic acid ALA
- ALA ⁇ -aminolevulinic acid
- ALA is generally known as the precursor of protoporphyrin IX in the formation of the blood pigment (heme biosynthesis).
- the previous clinical use of ALA was limited to certain metabolic diseases (porphyrias), where it proved unsuccessful. For example, Okuda et al. (Hepatology 1991 , 14, 1153-1160) on the treatment of patients with Gilbert syndrome (Behcet's disease) and healthy subjects.
- ALA is harmless as a substance. No toxic reactions were observed with intravenous administration of 0.23 mg ALA (Okuda et al., Hepatology 1991 , 14, 1153-1160, see also Kennedy et al., J. Photochem. Photobiol. B., 1990 , 6, 143-148). According to Berlin et al. (Biochem. J. 1956 , 64, 80-90 and 90-100), phototoxic reactions were only observed for 1 to 2 days in healthy volunteers at higher doses. In the context of various animal toxicity studies (Lima et al., Can. J. Neur. Sci. 1981 , 8, 105-114; Arnold et al., Food Cosmet. Toxicol. 1975 , 13, 63-68; Kennedy et al. , ibid 1976 , 14, 45-48) no negative symptoms regarding direct toxicity, photosensitivity, theratogenicity or subacute toxicity could be observed.
- the effect of ALA is based on the stimulation of the body's own Porphyrin.
- the use of ALA according to DE-OS 42 28 106 is based on the knowledge that ALA is topically integral Application to the mucous membranes of hollow organs selectively from Tumor tissue is absorbed and enriched and only there leads to an increased porphyrin formation and concentration, while the healthy tissue remains essentially unaffected. It has been shown that the enrichment factor compared to healthy tissue up to 20: 1, with the Result that the fluorescence of the tumor or pretumor islets can be seen even with the naked eye. On the previously necessary elaborate image processing systems can be dispensed with become.
- ALA will not targeted to the already recognized tumors to be treated applied, but it becomes the whole lining the hollow organ Mucous membrane wetted homogeneously.
- the tumor selective absorption when using ALA can not only early bladder carcinomas can be detected (integral Fluorescent labeling), but it can be followed by integral radiation to the bladder selectively the tumorous Lesions are destroyed (integral therapy). So in itself stands for the first time a therapy for precancerous and cancerous Lesions are available due to the lack of Possibility of diagnosis in the early stages of the disease were not treated. So far for e.g. bladder tumors observed recurrence and progression rates can be Crucial use of ALA for diagnosis and / or therapy reduce.
- ALA solutions are used with an active substance content between 10 and 33% by weight applied. Such ALA solutions are even in production not stable immediately before use and decompose into shortest time.
- DE-OS 42 28 106 proposes for diagnostic Application ALA in 3% aqueous solution to apply which to a neutral pH using sodium bicarbonate as a buffer is set.
- the Concentration of the neutral buffered ALA solution up to 10% be.
- solutions of ⁇ -aminolevulinic acid hydrochloride which already has a pH value at a concentration of 1% have between 2.2 and 3.2, to a strong, for the Patients' unbearable burning.
- the pH of the ALA solution must be between 4.8 and 5.2 in order to achieve both good compatibility and sufficient stability.
- a pH above 5.2 leads to the instability of the ⁇ -aminolevulinic acid, at a pH below 4.8 the side effect profile worsens significantly.
- the physiologically compatible buffer solution is preferably added to the sterile ALA lyophilisate shortly before use. Certain concentration fluctuations inevitably occur, which can be of the order of magnitude of ⁇ 10%. In other words, this means that when a 3% solution is prepared, the actual content can vary between 2.7 and 3.3%.
- the invention accordingly relates to a topically applicable Medicines for the integral diagnosis and / or therapy of Tumors in hollow organs based on ⁇ -aminolevulinic acid, where the drug is characterized in that it is ⁇ -aminolevulinic acid contains in an aqueous solution, which by a physiologically compatible buffer solution to a pH of 4.8 to 5.2 is set.
- the pH is preferably determined by a physiologically acceptable acid and sodium hydrogen phosphate a pH value of 4.8 to 5.2.
- the physiologically tolerable Acid is preferably hydrochloric acid.
- a special one advantageous embodiment of the invention is that 6-aminolevulinic acid is used as the hydrochloride.
- the drug solution is only immediately before the application from ⁇ -aminolevulinic acid hydrochloride in the form of a Lyophilisate with the addition of the sodium hydrogen phosphate buffer solution prepared, the drug in the form of the doctor a combination pack is made available.
- the combination pack is already the Parts of an arrangement which, when used for instillation of the Can serve drug.
- the drug is for diagnosis and / or therapy of the urothelium and central nervous system (preferred of the different brain areas) as well as for the integral Diagnosis and / or therapy of hollow organs such as the bladder (Urinary tract), the respiratory tract, the peritoneal cavity, the gastrointestinal tract, or the female genital tract, where the urinary bladder and female genital tract are preferred in Come into consideration.
- the application can - for example in the bladder - either done topically intravesically or in a preferred Embodiment done by instillation of the ALA solution.
- the hollow organ or the affected area is included in the diagnosis Light of the wavelength 390 to 430 nm, preferably 410 nm, irradiated integrally so that tumorous lesions fluoresce.
- Filtered light can preferably be of a wavelength of 406 nm can be used.
- a krypton ion laser is particularly suitable.
- an Nd: Yag laser neodymium: yttrium aluminum garnet laser
- a sterile solution of 5.4% by weight Na 2 HPO 4 .12H 2 O in sterile water was prepared.
- the pH of this phosphate solution was approximately 9.
- the 3% ALA solution with a pH of 4.85 was at Well tolerated instillation into the bladder of patients. In particular there was no uncomfortable burning sensation like this unbuffered ALA solutions is observed.
